	@config
	class CSVSourceConfig(FileSourceConfig):
	key: str = CSV_SOURCE_CONFIG_DEFAULT_KEY
	label: str = CSV_SOURCE_CONFIG_DEFAULT_LABEL
	labelcol: str = CSV_SOURCE_CONFIG_DEFAULT_LABEL_COLUMN

Add a config option which is a list of strings, which are the column names which should have their data replaced with the contents of the file for which they had the filename of as their value initially.

Lines 192 to 194 in c0899bc

	# Write the features
	for key, value in repo_data.get("features", {}).items():
	row[key] = value

If key (column name) is in the new config (files or something) then do

row[key] = pathlib.Path(value).read_bytes()

Make sure there is a testcase for it.
